Waiting, crowding, jostling and shoving. Shoulder bags, laptop bags, messenger bags. “’Scuse me, would you mind getting your backpack out of my face?” Switching from the “7” to the “44”? Quick, jump out the bus door, sprint across the train station plaza, scurry down the stairs while keeping an eye on the “Next train arrival” sign. Made it! Hey, mind the gap! These days, buses, streetcars and subway trains in the eastern Ruhr region get much better to their destination.
The improvements are the result of a joint project between Dortmunder Stadtwerke AG (DSW21), Bochum- Gelsenkirchener Straßenbahnen stock company (BOGESTRA) and Straßenbahn Herne – Castrop-Rauxel GmbH (HCR). These public transit companies collectively rolled out a computer-powered traffic management system for buses in their operating area and extended it to trains and light rail last year. The cloud-aware Intermodal Transport Control System (ITCS), which is based on TETRA digital radio, represents a new generation of cross-company traffic control system communications. Norbert Grossek, Head of Strategic IT Projects at BOGESTRA, explains what that means: “By integrating light rail into our management system, we can provide better everyday reliability for passengers in the region of BOGESTRA and DSW21, which number 300 million each year. Our customers benefit directly from real-time passenger information and from making more connections when switching between trains, light rail and buses.”
In general, public transit systems are under tremendous pressure from three different sources. First, the traffic infrastructures in metropolitan regions and megacities like London, Paris and New York are bursting at the seams. The Ruhr region, with nearly 5.5 million inhabitants, is no exception. Its available capacity is virtually exhausted. Even the smallest disruptions and unexpected breakdowns cause delays that often affect downstream trains, buses, streetcars and subways for hours to come. There’s no relief in sight, either: in the future, public transit authorities will have to transport significantly more passengers with their current rail and road systems. The burgeoning passenger numbers will be next to impossible to handle if there are any interruptions in service.
It doesn’t help that customers are getting more demanding, too. They know about real-time planning and communications and so expect trips and commutes to be perfectly coordinated by smart mobility solutions. To complicate matters, passengers move seamlessly from trains and buses to car or bike sharing programs. Deutsche Bahn has responded by becoming Germany’s largest car sharing provider (Flinkster), ahead of car2go, DriveNow and other competitors, as well as the nation’s most successful bike rental service (Call a Bike). Everything can be planned online or in smartphone apps. Customers also expect exact, accurate information on bus and rail delays, actual arrival times and alternative transportation and connection options. Transit providers are left with no choice but to accommodate customers with intermodal mobility solutions that make their services simple, reliable, flexible and attractive.
An analytics solution in the ITCS core tracks all the movements for each public transit operator in real time. Timetable data is constantly checked against current traffic conditions and the vehicles’ regular status reports. The data is used to forecast estimated arrival times and the knock-on effects for possible connections. And that’s the first step toward predictive analytics. Passengers can look up all the arrival and departure times that they need in the app or on the displays located along the more than 3,100 miles of roads and railways used by the KöR-vehicles connected to the system.
To ensure this information is available everywhere, the T-Systems experts had to outfit all the tunnels in the railroad system – over ten kilometers in total – with redundant TETRA digital radio communications technology with at least one fallback level. They also had to implement secure, encrypted data communications and link ITCS to the emergency services network used by the police, fire department and rescue services. “This new intermodal, cross-company communications solution that interlinks public rail and road transit systems can do much more than manage everyday traffic flows,” explained Thomas Preußner, Head of the Rail & Transport Management Solution Center at T-Systems. “Integrating rail services into the traffic management system also improves overall traffic flows and every passenger’s transportation options during trade shows, soccer games or any other of the large-scale events that happen all the time in a densely populated area like the Ruhr region.” Not to mention the twice-a-day rush hours that often seem to flow seamlessly into one another.
ITCS’s benefits – full multitenancy and rapid integration – haven’t been lost on other regional transit companies, either. One has already knocked on the door: Verkehrsgesellschaft Ennepe-Ruhr mbH (VER) recently issued a call for tenders to connect to the system..
